  • Bentonite

    Bentonite is a clay generated frequently from the alteration of a tuff or volcanic ash, consisting predominantly of smectite minerals, usually montmorillonite. Smectites are clay minerals which consist of individual crystallites that are actually three-layer clay minerals. Common names for smectite include montmorillonite or sodium montmorillonite ("sodium bentonite" or "Wyoming bentonite") and swelling bentonite ("Western bentonite").

    There are three types of bentonite occurring naturally:
    1) Natural Calcium Bentonite,
    2) Natural Sodium Bentonite and
    3) Sodium Activated Bentonites.

    The majority of bentonites that can be find worldwide are calcium bentonites. Calcium bentonites are often characterized by much lower swelling and liquid limit values compared to natural sodium bentonite. Natural sodium bentonites have sodium as the predominant exchange cation and are characterized by high swelling, high liquid limit and high thermal durability. Sodium activated bentonites are produced by the substitution of calcium ions by sodium ions. This transformation can be achieved by the addition of a soluble sodium salt to calcium bentonite.

    The special characteristics of bentonite (swelling, water absorption, viscosity, thixotropy) allow this material to be used in a wide range of industries and applications:
    - Foundry Industry (mould sand binder)
    - Construction (waterproof diaphragm walls, filler for GCL…)
    - Drilling (bentonite slurries and injection grouts)
    - Agriculture (mycotoxin absorber and binder in animal feed; used as well for soil treatments and in horticulture)
    - Food Industry (clarification of wines and fruit juices)
    - Cat Litter and Desiccant.
